Animaniacs - Once There Was A Man Named Oscar

[Jeremy]

This has the kind of appeal you'd expect from a much older game than it is.

Animaniacs (Sega Genesis version) wasn't what I'd call a good game. And most of the music isn't good music.

But the last level's music is really catchy - to the point that I remembered the tune two decades later - long after forgetting everything else about the game. Hearing that made from a catchy semi-epic jingle into an actual well-arranged song would be a real treat.

This particular earworm can be found here:

starting at 1:05.

...huh. Actually, looking it over, the music from the closing credits might be an even better candidate:

starting at 1:44.
